Application med. August 21, 1924. Serial'No. 733,450.

This invention relates to amachine for making tire carcasses of the typewherein 'a strip or web is wound on a rotatable member,

it being particularly adapted for use in con-l nection with a rotatingmember that is curved transversely, such as a core. U

One object of the invention is to provide an improved guide shoe for thematerial,

whereby it may be delivered to the rotatable.

Another object of the invention is to pro# vide a guide shoe of simpleconstruction capable of (1) guiding the carcass material with minimumfriction and (2) flexing transversely so as to deliver the material to arotatable forming member Without distorting it.

Other objects of the invention will be apparent to those skilled in theart to which my invention relates from the following description takenin connection with the accompanying drawings.

24 indicates bead rings (only one being shown) arranged to be clamped bydevices 25 V26 indicates as'an entirety bead rolling downdevices'preferably-mounted upon an arm 26a pivoted at its inner end tothe standard 3. The rolling down devices include rollers 26", whichengage the bead portions d of as it 1s found on the core 17.

'las

the web (see Fig. 8) to press them against the sides of the core 17. Theconstruction of these nected at its lower end to the base 1, as shown at30. Intermediate its ends, the lever 29 is connected to a rod 31 whichcarries at 4its inner end a piston' mounted in a cylinder 32. Thecylinder 32 is provided with valved controlled4 ports for the admissionof compressed air or other medium, whereby the rod 31 may be operated toswing the lever 29 and thus move the rolling down mechanism 27- into andout of operating position'. The cylinder 32 is preferably trunnionedbetween-the standard '3 and a bracket 33, so that it may accommodateitself to the position ofthe lever 29 as the latter is operated. 1 34indicates a valve mechanism for controlling the compressed air to thebead rolling down devices 26, the body rolling down Vmechanism 27 andcylinder 32.?

- The body rolling down mechanism 27 forms the subject material of aseparate copending application Ser. No. 736,349 for which reason furtherdescription thereof will not be necessary.

35 indicates as an entirety a guide shoe disposed betweentheconsolidating mechanism 18 andthe core 17 and arranged to guide thebody portion of the web cZto the core, so that the bead portions dthereof may engage the sides of the core adjacent to the bead ringssimultaneously with or prior tothe engagement of the body portion of theweb with the core.

Of the shoe 35, 36 indicates a pair ofl spaced arms pivotally mounted attheir inner ends upon lugs 37' (only one Abeing shown) supported by thestandard 3 and plate 18". -The arms 36 preferably converge so as toconform to the transverse width of the web d as it takes on a transversecurvature durin its feeding tothe core 17, each of said arms einfrpreferv ably formed of two strips 36?, 36?, the latter being connectedat their outer -ends by an arc shaped member 38 preferably formedintegrally with the elements 36".

- 39 indicates a rod connected atits opposite ends to the inner ends ofthe arms 36 so as to maintain them in spaced relationship. The elements36a, 36", constituting each arm 36 .may be Irignfidly secured togetherin overlapping relationship in any desired manner, butpreferably in anadjustable'manner, whereby the outer elements 36b may be moved endwiseof the inner elements 36a. For this-purpose the elements are `formedwith series of openings 36adapted to register with each other so thatone or more bolts 36? may be inserted therethrough and engaged by nutsA36, thereby serving to clamp the elements 36a, 36", in

face'to v.face engagement. v 40 indicates aroller rotatablymounted'between'the arms 36 and substantially .midway between theconsolidating mechanism. 18, or that roll 18Il thereof from whichv theweb d -is delivered, andthe arc shaped member 38.

The vroll 40is loosely mounted on a shaft 41 supported at itsoppositeends in standards 42, each standard being adj ustably connected at .itslower end to the adjacent arm, 36 inanyV desired manner, but preferablyby the following mstrumentalities ,43 indicate aseries of openingsformed vin the element 36", and

,spaced to register with a pair of screw thread--V ed openings formed inthe adjacent bracket 42 so that screws 44 may be inserted therein `and'the bracketsecured to vthearm 36. By providing a plurality of openings43 in each arm 36, 1t. will be fseen that the brackets 42 may be movedllongitudinally of the arm 36 toward and from the delivery end of theshoe, -z' so'that the materi l will be supported at any desiredpoint-betw en the consolidating mechanism and the are shaped member 38;The vopenings 43 are-preferably formed in the strip 36", so thatmovement or adjustment thereof willalso move or adj ustl the roller 40with it,

since in most instances it will not be necessary to adj ust the roller'relative to the" delivery end of the shoe, altho this is provided for,as

above set'forth. To provide for the openings 43. the elements 36" are'made somewhat wider than tbe element 36a. 47 indicates-aiexible shoesection extending outwardly beyond the are shaped section 38 and adaptedto extend over a portion of Y the core 17 so as-to guide the bodyportion of f the web and 'the side edges or bead portion thereof intocontact with the corein the'manner to be later set forth.The-flexible'section.

47pre'ferably comprises 'a plurality of spaced resilient strips 48extending longitudinally and rigidly connected attheir inner ends to theare shaped member 38 and transverse re'- silient elements 49 connectedto and extending moaosa across the strips 48. The longitudinal elementsare formed from metallic strips, whereas the transverse elements49preferably coinprise sections of resilientwire, such as piano wire,and co-operate with the strips 48 to permit flexing of that portion ofthe shoe' which delivers the web to the core to permit it to conformapproximately Ato theshape of the core and thus deliver the web inshaped condition ready for application thereto.' As the delivery end ofthe shoe is resilient, it tends to expand the web outwardly and thus tohold it out of contact with the core until the web passes the outer orfree end of the shoe, Accordingly, l am enabled to hold the body portionaway from the core 17 until or following the engagement ofthe beadstherewith and operation of the bead rolling down devices 26, as shown inFig. 8. The transverse elements 49 are preferably held in position byproviding each strip 48 with a pair of slits 50 and lbending the section50a of the metal between the slits laterally to Aform la bearing throughwhich one of theelements 49 extends; the slits being arrangedon theseveral strips to bring the bearings in alignment. By reference, themetal sections between alternate pairs of slits are bent in oppositedirections,

so that alternate transverse elements 49 are upon opposite sides orfaces of the stripsl 48 (see Fig. 4), the purpose of which will laterappear. The opposite ends of the transverse elements 49 may be securedto the outer strips 48 in any desired manner to prevent endwis'emovement of the elements, as well'as to prevent spreading of the strips48, such securing being preferably provided for by bending the ends ofeach element 49 around the outer -strip as shown at 51 in Fig. 5.

52 indicate devices for maintaining the strips in spaced relation sothat vwhen the shoe is flexed by the feeding of the web (i to the core17 it will conform approximately to the shape of the core in crosssection rather'than become distorted intermediate its side edges. Thedevices 52 preferably comprise a plurality of sleeves surrounding eachof the transverse elements 49, one being interposed between adjoiningstrips 48 and engaging therewith at its opposite ends-see Fig. 5.

53 lindicate rollers each rotatably fitting one of the sleeves 52. Bymounting the transverse elements 49 u pon opposite sides of thev strips48 I provide spaced anti-friction devices on'both the upper and lowersurfaces of the delivery section of the shoe. By this.

arrangement, the rollers on the upper side of the shoe serve asanti-friction devices between the web d and the resilient or flexiblesection of the shoe as the web slides -thereovcr;

`whereas the anti-friction devices 53 on the lower surface of the shoeroll on the core 17 as the latter rotates and thus support the deliveryend of the shoe and at the same time maintain the free outer'end thereofat a predetermined distance from the/surface of the I' l core 17. Asshown in the drawings theA rollers 53' are of less length than thevspacing devices 52 so that they may rotate freely thereon withl outengagement with the side walls-*of the strips 48 or being wedgedtherebetween when the shoe is Hexe l 'Y As will b e understood fromFigs". 2 and 7, the supporting and guiding roller 40 is curvedlongitudinally or from end toendto conform to the transverse shape ofthe web d' as it' l with minimum friction. My. shoe construe-i tion isparticularly adapted for delivering the carcass material to a core sinceit isresilient and capable of conforming itself tothe shape thereofwithout permitting distortion Vor wrinkling 0f the material; this isequally true where the material is of the composite type Vin y which thebeads are incorporated therein and the latter'are pressed inwardlyagainst the opposite sides of the core. In winding a carcass frommaterial of this characterfthe beads are wound helically in side by siderelation and must be rolled down prior to or at the same time, astheapplication of the body ortion ofthe material. In the operation o myshoe lt am enabled to guide Vand support the body portion of thematerial out of contact with the core until or following the engagementof the bead rolling down devices with the beads to press them againstthe sides of the core adjacent the bead' rings.
